We were discussing the new aqara MM wave sensor, the FP300, Which, as of the time of this posting has not yet been released. A side discussion started about the Tuya ZG-204ZM sensor, which got pretty confusing and was hijacking the thread. So I have moved the Tuya discussion into its own thread here.
That isn’t “new”!
I´m using and testing this ZG-204ZM sensor with @Mariano_Colmenarejo Motion Sensor MC edge driver and is working very well. Its presents itself as a single zone motion sensor and use the PIR to detect large movement (someone entering the zone) and then activate the mmWave sensor. After that, the mmWave keep working to detect small/stationary movement and the “Motion/Presence” status stay´s until there is no more presence detected by the sensor.
Obs.: It also reports illuminance changes every 1 minute.

That’s nice and all, but is it Matter over Thread?
Checkmate!

I’m not in the hype of matter over thread yet! My V2 hub is working very well with zigbee

I bought this. Tested it with Mario’s driver…meh. Did not get the impression it was anything more than a PIR sensor … At least with Mario’s driver. It would not keep “motion detected” even when it placed 6 feet in front of me, and going out of my way to make sure I was moving around.
It activated well, that’s about it.
Have you really managed to get a fp300 already?
I don’t think it’s been released yet.
If you did get one, where did you buy it?

Try this driver:
Sorry was replying to @marcos.scheffler about the tuya sensor.

I have 4 of them and 3 work like a charm.
Devices stays with “motion detected” status all night while we are sleeping, using Mariano’s driver.
1 device aren’t correctly detecting the stationary movement, i’ll connect it to Tuya hub again and reset its sensitivity settings, then i tell you if it’ll as supposed.
I have one more to try. I also don’t have a tuya hub wonder if that’s the issue?
Thanks @JDRoberts !

In smart life app with tuya hub the device have all this sensitivity configs (this is the default):
In my case, for this particular sensor that aren’t working before, after pairing again with the tuya/smart life app, reseting the default settings and doing some trial and error, believe that i’ve found a config that works. One thing to notice is the change of the “presence keep time” parameter from 30s to 60s:
My sensor is in a restroom, so i want to detect micro movement like breathing to keep presence while someone are sleeping and, from device manual:
Is’ Presence Keep Time 'set as small as possible?
Answer: No, it is not possible because it takes about 5 seconds for the radar to detect and lock micro movements, and 40 seconds or more for locking breathing.
For a detailed explanation about the parameters:
Ha kinda wish you posted about having the tuya hub before I purchased these…
**** EDIT: I’ve corrected the parameters used for my bedroom example, the parameters posted prior are from my living room sensor. My bad.
Not to let anyone confused, i’ve added the two examples. ****
Returning to feedback on my tests with these sensors (all of mine have “_TZE200_kb5noeto” fingerprint)
The most important detail: “sensor positioning is key to proper functioning”.
The sensor has a wide aperture (FOV = 120°) and is very sensitive to micro-movements such as curtains or plants swaying in the wind, … therefore it needs to be positioned so that it is not facing these moving objects, as this can cause the sensor to get stuck in presence detection. The angle and distance in relation to the target to be detected are also important (if you want to detect someone sleeping, for example, it is better to install it in a higher position). Regarding distance, although it can detect initial movement up to 10 meters, the mmWave detects movements up to 8 meters, and a static person up to 4 meters. This can be verified in the sensor manual.
*Blue line is the range for stationary target detection.
Sensor also has a precision of 0,2m to 0,5m.
With all this in mind, after changing the position of my test sensors, I reconnected them to the Tuya Hub to adjust the settings. Factory reset them multiple times.
Bedroom:
For my bedroom, i’ve placed the sensor in the ceiling (2,5m high) in the middle of the room (2,5m x 3,3m), facing down just a little bit inclined towards the bed, and than set the mmWave radar detection distance to 4,5m (4,0m - 5,0m detection range), with this distance the FOV can cover all the room. Motion sensitivity (PIR) to default 5x, stationary detection sensitivity to 8x, motion detection = radar and PIR (pir detects large movements and mmWave locks in stationary targets).
Living Room:
In living room i’ve placed the sensor in the corner of the wall (2,3m high), facing the center of the room (back to the curtain), diagonal to the couch, that is my main target. Set the mmWave radar detection distance to 5m (4,5m - 5,5m detection range), with this distance the FOV can cover all the room. Motion sensitivity (PIR) to default 5x, stationary detection sensitivity to default 6x, motion detection = radar and PIR (pir detects large movements and mmWave locks in stationary targets).
For both bedroom and living room i set “presence keep time” to 300s, so it will release the presence status after 5 minutes of no motion detected.
This gives the mmWave radar more time to re-engage the target if tracking was lost in case of very small movements like breathing and heartbeat.
For my office, i set this parameter to 60s that is enough for a room where targets will not remain stationary for large periods of time. The other parameters of the office sensor are equals to the living room.
And thats it, sensor will stay in “present” state through the entire night while sleeping in bedroom, also when siting in the couch on living room or in my desk in the office and returns to “no present” 5 minutes after leaving the bedroom/living room or 1 minute after leaving the office.
